At fixed feed quality, Coker yields mainly depend on 3 operating parameters, which are Coke Drum top pressure/ CokeDrum top temperature and recycle ratio. If you maintain these three parameters consistently then the yield in coke drum overhead will remain same. However, you may see a change in liquid yields due to poor separation, which is dependent on your fractionator temperature and pressure profile.
